Webb18 jan. 2024 · However, due to the lack of imagery information in low-resolution (LR) images, single-image super-resolution (SISR) is an inherently ill-posed problem. Especially, it is difficult to reconstruct the fine textures of HR images at large upscaling factors (e.g., four times). Webb14 dec. 2024 · A study of ill-posed problems naturally begins with linear operators as the theory for the linear case is rather complete. We will therefore follow this path and refer to the classical book of Engl et al.

WebbTo address the fact that the problem is inherently ill posed, many methods impose a prior over human poses. Unfortunately these priors admit invalid poses because they do not model how joint-limits vary with pose. Here we make two key contributions. First, we collect a motion capture dataset that explores a wide range of human poses.
